What are water spots?

Water spots on a car are mineral deposits that remain on the surface of the paint after the water has evaporated. They can appear as small white or light-colored spots, streaks, or circles, and are often caused by hard water or mineral-rich tap water that has been left to dry on the surface of the car. Water spots can also be caused by acid rain, bird droppings, or other environmental contaminants.

If left untreated, water spots can become difficult to remove and may even etch the surface of the paint, causing permanent damage to your car's finish. To prevent water spots from forming, it's important to dry your car thoroughly after washing, especially in areas with hard water. You can also use a water softener or filtered water to reduce the mineral content of the water you use to wash your car.

If you already have water spots on your car, you can remove them by using a dedicated water spot remover, which typically contains mild acids or polishing agents that break down and dissolve the mineral deposits.
